A volcanic landscape in the Tibesti Mountains of Chad shows some mysterious shapes. However, science can explain mysteries in satellite images. The octopus-shaped feature consists of ancient volcanic flows. In the crater below it, what looks like a face is bright salt deposits.

Green shades seem to be bubbling up like a lava lamp on the left side of this image from northeastern Kenya. The right side is like rusted metal. The dark green is the result of geologically recent lava flows, and the other colors are different types of soils. Even with few defined shapes, the piece has a strange beauty.

Soft colors contrast with harsh terrain in southwestern Saudi Arabia, near the border with Yemen. Calming blues and purples seem to collide with an angry orange in this rich tapestry of colors, which are the result of the region’s complex geology. The wild shapes in this busy landscape lie in a region known as the Asharah fault zone.

Fluorescent colors dominate this dreamlike scene. The orange shapes look like glowfish in a fanciful underwater world. Those glowfish are actually clouds, and the neon green represents mountains, including Mount Rainier, near Seattle, Washington.

In a remote part of the Western Desert in central Egypt, highly eroded plateaus rise from the desert floor. The bright speckles are ancient dry lakes, the salt deposits reflecting brightly. Long ago, water flowed off the plateau, forming the breaches seen on the plateaus’ edges. This desolate land between oases is surrounded by extensive sand dunes.

These orange shades and ragged shapes give an impression of moodiness. The jagged scars are extensive valleys carved by water flowing from the Andes Mountains in northern Chile. The crater in the lower right is the volcano Cerro Guachiscota.

The northern end of Isla Isabela in the Galapagos looks like a seahorse with warts—with an eye painted in the ancient Egyptian style. The island was formed by the merger of six volcanoes. Wolf Volcano is the prominent one in the center; Ecuador Volcano is the one that forms the seahorse’s mouth. Past volcanic flows radiate from the large craters.

This Landsat image looks like a bold watercolor. Yellow dances across the darkness with muted violet underneath. With a kind of science-fiction flair, this scene shows a portion of the Qattara Depression in Egypt.

Extensive farmland in northeastern China shows a predictable pattern of vertical shapes. But on closer inspection, the shapes begin to look more random, with variances everywhere. Look closely to be surprised by patterns and broken patterns.

Vegetation appears red in this piece, which moves from dark to light in the Atlas Mountains of Morocco. The vegetation grows along streams, which seem to follow a tortured course through the ridges and valleys before wandering through the desert.

In far northern Canada, pulses of freshwater flow down rivers after inland ice and snow melts. These pulses, known as a freshet, carry huge amounts of sediment. The sediment seen in this image flowed into the Beaufort Sea from the Mackenzie River, the longest northward-flowing river in North America.
